Peritoneal carcinosis is a local/regional dissemination of digestive malignancies, gynaecological malignancies or other forms of cancer with or without proof of the existence of systemic metastasis. Mode of formation and evolution is controlled by several factors, mainly physical (the primary tumor, presence or absence of ascites, peristaltics, peritoneal fluid absorption, gravity, intraabdominal liquid) and of minor importance the biological factors (aggressiveness of cancer). We analyzed 17 cases of carcinosis from pancreas neoplasia, operated and neoperate in history. It sought to determine the distribution of peritoneal metastatic implants and quantification of peritoneal cancer index (PCI), based on imaging examinations and by surgical exploration (laparoscopic or laparotomy). We evaluated the distribution and redistribution in such conditions depending on tumor location, gender of patients, surgical intervention and concomitant pathological conditions.
